"The goal of the operation was simple: We wanted to get as many illegal and unwanted guns off the streets of Solano County as possible," Kreins said in a statement today.

"We all know that these very firearms are often used to commit violent crimes against our fellow citizens and in a variety of tragic scenarios, including suicides," Kreins added.

A similar gun buyback in Santa Clara County last weekend had a starting budget of $150,000. In the end, the Santa Clara County sheriff's department said they received 1,116 guns, which included 47 assault weapons. They gave out about $114,000, which means they had money left over.
